Vim code

More obfuscated programming

VI VI VI - Editor of the beast.

Vim can be programmed, just like emacs can. But I'm not talking about the fancy-schmancy .vimrc-style scripting. I'm talking about copying parts of the buffer into registers, and then executing the contents of those registers as if they were macros.

If you don't think it's insane yet, wait till you see the source code:

Note: If you have configured vim to use alternate keyboard mappings, these programs won't work. If this is the case, start vim with the standard mapping, i.e. "vim -u NONE mandelbrot".

So now I'll leave it to someone else to implement an ELisp interpreter. =)

You must have a lot of time on your hands. Fun snippets though, must've been a blast to get working. ;)

You really should get out more often.
By the way, I am having fun looking at some of the crazy stuff you are doing

Hanoi works, but mandelbrot just keeps writing strange stuff to my console.

That's purely insane O_o
If only there was an iovvv (think of ioccc), maybe it's time to setup the chalenge.

I didn't realise at first it was drawing the set but it was on my 170MHz dear host. switching to a 3GHz pc helps rendering it faster :p

congrats anyway

I'm just fascinated with how clever these are. I discovered them about a year or so ago, and find myself coming back every few months to play with them again.

Bravo!

I feel quite stupid but I can't get these to work. If I open them as regular files and type GY@ I see an @ in the statusline but nothing else happens. If I for example press Enter I get told that '^M' is an invalid register name.

*Hides in embarassment*

You need to type the double-quote character as well.
